I just ran my Pro XXL yesterday with no problems. I fired it back up this evening to cut keyholes for some plaques I’m cutting. After running the program 3 times, the 4th, 5th and 6th run made it to the top of the keyhole and when it started backing back down to the initial plunge point, I get a pop up saying, “Cutter Not Connected”. Then when I click on Connect to Cutter, I get a pop up saying, “Cutter Not Responding”. But if I power down the cnc and then hit connect, it connects but does the same thing again.
Also, I did check the brushes in the router, and they look dang near new. I made sure to clean the board and the connections, as well as the laptop.
Any suggestions as to what the issue might be?
What is EMI? Is that the control board?

“Electro-magnetic Interference”. It is usually caused by static electricity build-up (usually fixed by properly grounding the dust collection system), or excessive electrical arcing (perhaps from worn-out motor brushes).
Can also be affected by exterior factors - for example, low humidity will make static electricity much worse.
